JAMES WILLIAM DEGKERT, OF OAKVILLE, CANADA.

HIDE-WORKING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 791,015, dated May 30, 1905.

Application filed July 21, 1904. Serial No. 217,455.

To (LZZ whmn it may concern:

Be it known that I, JAMES WILLIAM DECK- ERT, leather-splitter, a citizen of the United States of America, residing in the town of Oakville, county of Halton, Province of Ontario, Canada, have invented certain new and useful Improvements in Hide-Working Machinery, of which the following is a specification.

My invention relates to improvements in hide-working machinery; and one object of my invention is to design a machine that can be used by changing certain parts for unhairing, unfleshing, and stoning hides.

Another object is to construct my machine so that it will adjust itself to the different thicknesses of the hide, so that same will be thoroughly prepared for leather.

Another object is to regulate the pressure of the hide against the cylinder.

A still further object in my preferred form of invention is to horizontally support the hide and first move it with the rotation of the cylinder and then to return itagainst the rotation of same, thus insuring the most effective work being done thereon; and it broadly consists of a rotary cylinder, means underneath same adjustable to the differentthicknesses of the hide placed between same and said cylinder, so that thin as well as thick portions thereof will be thoroughly prepared for leather, and a flexible bolster underneath said cylinder and upon said means for supporting the hide, the flexible bolster being movable in a straight or curved line transversely to the axis of the fixed rotary cylinder and the said adjustable means.

My invention further consists in its preferred form in providing a particular carriage for the bolster and in providing means for reversing same and other combination of elements, as hereinafter more particularly explained.

My machine as illustrated is equipped for unhairing hides, and I shall describe its principle in performing that function. Of course it will be understood that by changing the knives or stones in the cylinder the machine will perform the different classes of work before enumerated.

Figure 1 is a front side elevation of my machine, parts being broken away and parts in section. Fig. 2 is a longitudinal vertical section on the line 0 (Z, Fig. 1, showing a hide clamped in position. Fig. 3 is an enlarged perspective view of the under side of the preferred form of carriage for the bolster. Fig. 4 is an enlarged vertical section on the line a b, Fig. 1; and Fig. 5 is a detail view, partly in section, of the preferred form of sectional ring-roller.

1n the drawings like characters of reference indicate corresponding parts in each figure.

A is the bed of the machine, and G and C the head blocks suitably secured thereto. Suitably mounted in these head-blocks is the cylinder D. On one end of the shaft E of the cylinder is the drive-pulley F, which is always driven in one direction.

G, the roller, made ofresilient material, is suitably mounted in the head-blocks underneath the cylinder, and each end of the shaft H of same is provided with pinions I and I, which mesh, respectively, with the gearwheels J and K, keyed to the main shaft L, held in suitable bearings in the said headblocks.

M and N are the front and rear brackets, suitably supported to the bed A and upon which are respectively secured the plates P and 0. These two plates, together with the cylinder D-and the roller Gr, form what I call a ring-chamber Q. In this ring-chamber and resting upon the roller G is a sectional ring-roller B. By means of the plates P and O it will be understood that the axis of the sectional ring-roller will always be parallel with the axes of the roller G and the cylinder D. S represents suitable extensions of the machine-frame and are designed to support the carriage T, to which is suitably secured the bolster U. The cylinder D is revolved quite rapidly and always in the samedirection, as shown by arrow, and the roller G is revolved at a very much lower rate of speed, and consequently the sectional ring-roller R revolves slowly. The sectional ring-roller is revolved by means of the roller Gr, bolster U, and cylinder D. Part of the hide is placed on the bolster in the position shown with the hair uppermost, and by means of any suitable clamp V, suitably hinged to the carriage, as

at Q), same is secured to said bolster. As the gear-wheels J and K mesh with the racks j and 7c of the carriage T, it will be understood that the said carriage will be moved in the direction indicated by arrow and the hide moved between the cylinder D and the sectional ring-roller R. Although I may use any construction of cylinder in connection with my hide-working machine, I preferably use the cylinder described and claimed in my application, Serial No. 212,672, filed June 15, 1904. For unhairing purposes the blades m and n are made of rawhide. By means hereinafter described when the carriage T is moved to the limit of its inward movement the gearing is reversed and the carriage is returned to normal position, which is shown in Fig. 2, and this operation is repeated. As the cylinder is always rotated in the same direction, it will be seen that I first move the hide with the rotation of the cylinder .and then return it against the rotation of same, thus insuring the most effective work being done thereon. If necessary, the described operation may be repeated several times. When the portion of the hide worked upon has been unhaired, the clamp V is thrown up into the position shown in Fig. 1 and the part of the hide held in the hide-box W placed and clamped in position and unhaired. Some of the most essential parts of my present machine are embodied in my application for improvements in machines for stoning leather, Serial No. 208,906, filed May 20, 1904. In this application the broad claims cover the combination of the stoning-cylinder with a sectional ring-roller operating thereunder upon a roller made of resilient material, the said ring-roller being used for the same purpose as the one employed in'the present machine. In this said application I also claim means for keeping the ring-roller parallel with the stoning-cylinder. I also claim the cam-pillars for regulating the pressure of the ring-roller against the hide through the roller made of resilient material. The said sectional ring-roller is firmly yet yieldingly'held by the roller G against the bolster and is constructed so as to keep all parts of the hide close in contact with said cylinder, as was described in the said application. As it is necessary to show fully the points of merit in the present machine, I shall describe the operation of its sectional ring-roller. The preferred form of the sectional ring-roller is made of a plurality of rings 6, provided with a central hole t, through which passes the spindle 6 As will be seen from Fig. 5, the rings 6 abut against each other and by reason of this and the collar t keyed on the said spindle, are held from longitudinal movement. t represents the end to each 0 her.

provided with flanges t, which overhang the collars t Sufiicient spaceis left between the collars't" and the inner side of the flanges 25 so as not to interfere with the movement of the rings. By theconstruction just described it will be understood that when a hide is being prepared if a thick portion thereof should pass between the cylinder D and, for instance, the rings 6 the said rings will be moved down, as shown in Fig. 5, and thus be more deeply depressed into the roller G, so as to permit of the passage of a thick portion of the hide; but yet by reason of the rubber cushion afforded by said roller the said rings will keep the hide in close contact with the cylinder. In case a thin piece of hide should be passing between any of the rings and the cylinder, from the operation just described it will be understood that that portion of the roller G underneath the rings between which and the cylinder the thin portion of the hide is passing will move said rings upwardly, so as to keep the thin portion of the hide in close contact with the cylinder. It will of course be understood that the bolster U is made of suitable flexible material that will permit of the operation just described. From the operation and construction just described it will be understood that my machine will adjust itself to ditferent thicknesses of the hide, so that it will be thoroughly unhaired. A represents plates suitably secured to the plates P and O for the purpose of preventing the sectional ring-roller R from moving out of the ring -chamber Q. In the construction shown the said plates are supported in position by means of tapered centrally-slotted blocks B, resting upon the plates P and O and underneath their lower ends and down through which pass the screws. B into the plates 0 and P. B represents screws which secure the free ends .of said plates to the plates P and 0. By means of the slotted blocks B and the slots 7) and b in the plates A it will be understood that these said plates may be moved to or from said sectional ringroller. In place of this construction I may make the brackets M and N adjustable, as described in my before-mentioned application.

In order to prevent the bolster from coming in contact with parts of the machine other than the sectional ring-roller and, further, in order to maintain its tautness, I provide suitable rollers G which may be held in bearings in any suitable manner in the machineframe. In the construction shown (see Fig. 1) the said rollers are journaled at their inner ends in the front bracket M and at their outer ends in the head-blocks, as shown at c.

In order that the carriage T may always travel in a straight line, I provide same with grooves D, in which fit correspondinglyshaped rails D secured to or forming part of the extensions S.

One end of thebolster U is secured to the cross-bar a) of the carriage T, and the other end of said bolster is secured to the movable cross-bar of said carriage. The ends of the adjustable cross-bar v operate in the slots '0" of the carriage. By means of the bolts 0: connecting the adjustable cross-bar o with the fixed cross-bar o and the nuts 0 on said bolts it will be understood that said adjustable cross-bar is moved in said slots, and thus the tautness of the bolster U is adjusted. Between the cross-bar a) and the cross-bar '0 is a space in which fits the head of of the clamp V. From Fig. 2 it will be seen that the said head of said clamp holds the hide in position. I of course do not confine myself to the construction of the carriage shown and described.

D represents water-pipes through which water passes in order to keep the working parts of the machine free from hair, &c.

It is necessary that the sectional ring-roller It be held at all points against the cylinder, and for that purpose I use any suitable means, preferably those described in my application Serial No. 208,906. Briefly stated, the shaft H has bearing in the sleeves O in turn held in the bearing-blocks 0 which have movement in the slots O, formed in the headblocks; Secured to or forming part of the sleeves O are threaded shanks 0 represents the top members of the campillars, and O the lower members of same, which are suitably secured to the bed A. As shown, both members of the cam-pillars are provided with a common core 0 in which is held the connecting-pin 0, around which the top member 0 turns. As will be seen from Figs. 1 and 2, the threaded shank O rests in the upper part of the core 0 As will be seen from the drawings, the lower end of the top members 0 are constructed with a camsurface 0 which coacts with a similar camsurface O constructed in the top of the members By means of a rod 0 suitably attached to the levers O of the top members 0, the said levers are moved so as to raise or lower said top members, and thus regulate the pressure of the roller Gr against the sectional king-roller. By means of any suitable arm 0 the rod O is operated.

WVhen the roller G is quite long, I prefer to use a king-roller G and -give same bearings in the cam-pillars before described, as clearly set forth in my application Serial No. 208,906. As shown in Figs. 1 and 2, I preferably operate the roller G from the gearwheel K, so that the direction of rotation of said roller will be changed when the carriage T is reversed.

F is any suitable support in which is held a rod F held in the position shown in Figs. 1 and 4 by means of the spring F held within said support.

F is a pivoted arm, the upper end F of which is in the path of movement of a number of pegs suitably held in the carriage T.

In the position shown in Figs. 1 and 2 the direction of movement of the carriage T is just reversed. As the adjustable cross-bar o of said carriage moves close to the head-blocks a pin abuts against the top end F of the pivoted arm F" and moves the beveled portion F thereof from the left-hand side of a beveled head F of the rod F 2 to the right-hand side of same, as shown in Fig. 4:. As the said pivoted arm is keyed to the shaft F held in suitable bearings, the movement of said shaft moves the arm F", keyed thereto, so as to operate any well-known friction-clutches F to throw the beveled pinion F in gear with the driveshaft F of the drive-pulley F thus operating the beveled pinion Ff, held in any suitable bearing F by its shaft F in the direction indicated by arrow. Keyed on the end of this shaft is a gear-wheel F which meshes with the pinion F on the end of the main shaft L and through same, and the parts before described reverse the said carriage. As soon as the cross-piece 1: moves close to the head-blocks the pin F (shown in Fig. 1) abuts against the pivoted arm F, moving same to the left-hand side of the beveled head F of the rod F thus operating the shaft F thus unclutching the beveled pinion F from the shaft F and throwing the beveled pinion F in clutch with said shaft, thus reversing the train of gear and said carriage.

It will of course be understood that I do not confine myself to the means shown and described for reversing the machine, nor to the means for transmitting energy to the roller Gr and carriage T.

By'means of the hand-wheels IE it will be understood that the shaft E of the cylinder D may be raised or lowered, as was fully described in my application Serial No. 208,906.

By means of the handle Gr" of the pivoted arm F it will be understood that the operator may reverse the direction of movement of the bolster at will.

It will of course be understood that the essential elements of my machine can be employed to advantage in machines differing in other respects from that herein shown and described for performing the various operations upon hides, and it must be understood that I do not, broadly, limit myself .to their use in connection with any particular construction or arrangement of other parts.

As will be noticed from the drawings, I preferably place the rollers G and It and cylinder D so that their axes will be in a vertical line.

I do not confine myself to the construction herein shown and described, as same can be altered in many ways without departing from the spirit of my invention.
